Battery Duralast or OEM Mercedes

These parts are New. Battery duralast gold

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

Duralast AGM. No leaking, minimal to no corrosion, god life, decent power, and most importantly it was readily available.

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

I bought a Duralast Platinum H5 AGM. I have read several instances of Subaru of America reimbursement.

If the battery dropped to 9V it is probably defective.

Drive a 2018 Nissan Rogue, about 80k miles. Have a Duralast Gold battery from Oct 2023, but live in central Texas where I hear batteries don't last as long.

I don’t have an AMG, but a 2024 CLA 200d and having battery drain problem is annoying to say the least and haven’t even had the car for a month when it all started happening. It’s been at the dealer for the past 3 days and no voltage drop there. They gave me the signal blocking key case and they upgraded the software and still can’t find the problem. Third visit in the month and new battery installed too.

same issue with daily driver 2021 E63. In this case though, the car doesnt give me a warning as much as the Mercedes app on my phone - it alerts to low battery -even critically low, but when I get into the car it starts and there is no message.

Just bought a new G63, same issue!
